NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 313,149, dated March 3,1885.

Application filed June 14, 1884.

To all whom, it may concern.-

Be it known that I, ARTHUR T. WVOODS, a citizen of the United States,residing at Champaign, in the county of Ghampaign and State of Illinois,have invented certain new and use ful Improvements in Nut-Locks; and Ido hereby declare the following to be a full, clear, and exactdescription of the'invention, such as will enable others skilled in theart to which it appertains to make and. use the same.

My invention relates to improvements in nut-locks used in connectionwith bolts and nuts which are applied for the retention of fish-plateson railway-rails.

The object of my invention is to provide a strong and durable and at thesame time inexpensive device, which, when properly adjusted, willsecurely lock and hold the nut to which it is applied in position uponthe bolt. It is of such form of construction as to be free from dangerof breaking by sudden strains or severe shocks, and may be readilyremoved or readjusted without injury to its structure. The manner inwhich this object is attained is hereinafter fully described, referencebeing had to the accompanying drawings and letters of reference markedthereon, which constitute a part of this specification.

Similarletters refer to similar parts through out the several views.

In the accompanying drawings. Figure l is a section on linemx of Fig. 2.Fig. 2is aside view of washer and nut-lock as applied to joint of rail,with straight fish-plate and square ing shown as removed from the rail.Fig. 4 is a side view of the device, in which the locking-plate is shownas provided with a notch suitable for hexagonal nuts. Fig. 5 is a sideview upon one'half the scale of Fig. 2, the locking-plate being turnedupward, so as to clear the nut, this being its position when the nut isbeing adjusted.

Referring to the drawings, a represents a washer, made of iron or othersuitable material, bent at a point intermediate of its ends, so as toform two right angles to the bent middle portion thereof, a hole beingpunched at a point near one of its ends to accommodate the bolt b, andthe hole h provided for the re- Fig. 3 is a plan of Fig. 2, the partsbe-- (No model.)

ception of the lockingplate c. The hole h may be either round, square,or of any other desired shape, depending upon the form of that portionof the locking-plate which is to pass through it. The rear end ofthelockingplate 0 is bent at right angles to its forward end, formingthe neck J, and is again bent at right angles to the neck, in adirection away from its forward end, so as to enable the bent portion topass through the hole It in the wash er. The opposite end of thelockingplate is provided with a notch, l m, of such form as to beadapted to the shape of the nut used. The length of the locking-plate issuch that when in the locking position shown in Fig. 2 the neck J willbear against the edge of the hole h which is farthest removed from thebolt 11, while its opposite end will be supported upon the nut by thelip in, the face Z being in contact with one of the edges of the nut, ornearly so, the nut being thus prevented from turning, while the corner kof the lockingplate bears against the fish-plate and prevents itsremoval without first slacking the nut,though, when desired, it may beturned in the hole h, so as to clear the nut and occupy the positionshown in Fig. 5. \Vhen detached from the bolt, the locking-plate 0 andthe washer a are entirely separate.

I do not wish to confine myself to any particular form of locking-plate,as it is evident that the notch in the same may be varied so as toconform to the style of nut used.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

In a nut-lock, the combination of the lockingplate 0. having the neck J,and bent at right angles to the neck in a direction away from itsforward end, with the washer a, bent as shown, and having a hole nearone of its ends for the accommodation of the bolt 1), and the hole h,for the reception of the locking-plate, substantially as and for thepurpose set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

ARTHUR T. \VOODS.
